Tony Cuesta (13 June 1926 — 2 December 1992) was an anti-Castro Cuban activist.
Initially a member of the 26th of July Movement and a close supporter of Fidel Castro, Cuesta in 1960 defected to the United States, and in 1961 was one of the founders of the anti-Communist paramilitary organization Alpha 66.
He later set up the guerilla group "Comandos L" (the L standing for Libertad) which operated out of Anguilla and, under his command, in 1963 sank the Soviet freighter Baku in Caibarién Harbour.
He had been attempting to smuggle men into Cuba in order to assassinate Castro when he was fired upon by a Soviet ship.
Rather than surrender he attempted to blow his ship up with a hand grenade, as a result of which he lost an eye and an arm.
